Williams Comfort Products JHW640SC Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW640SC is a combination wrench built for demanding trade applications where fastener integrity matters. It features a 1 1/4 inch open-end opening and a 17 inch overall length, giving technicians the reach and leverage needed on larger hex fasteners. The open end uses a SUPERCOMBO profile with machined grooves that redirect wrenching force away from fastener corners, while the box end uses a SUPERTORQUE design that contacts the flat faces of the hex rather than the points. The result is higher torque capacity with reduced risk of rounding or deforming fastener surfaces. Weighing 2.6 pounds, the wrench carries a high-polish chrome finish that resists grime and wipes clean between uses.

This wrench is suited for HVAC, plumbing, and mechanical contractors working on large-diameter fittings, flanged connections, gas valves, and structural fasteners commonly found in commercial and industrial installations. The 17 inch overall length provides sufficient leverage for high-torque applications without requiring a breaker bar extension. Licensed technicians and journeyman mechanics in the field will find this wrench appropriate for both installation and service work on equipment with 1 1/4 inch hex fasteners.

Key Features

• SUPERCOMBO open end with machined grooves directs force away from fastener corners
• SUPERTORQUE box end contacts flat hex faces, not points, for higher torque without deformation
• 1 1/4 inch opening accommodates large-diameter hex fasteners common in trade work

Compatibility

Designed for use with 1 1/4 inch hex fasteners in HVAC, plumbing, gas, and mechanical service applications.

Installation Notes

Use on de-energized or de-pressurized systems before applying torque to fittings or fasteners in live service environments. Ensure the correct jaw size is seated fully on the fastener before applying force to prevent slippage. A licensed technician should follow applicable trade codes, including IFGC or IPC where relevant, when tightening gas or fluid system connections. Inspect the wrench for cracks or wear before use on high-torque applications.
